Abstract

Crude aqueous solutions of glyoxal are purified by contacting the solution with an anion-exchange resin containing tertiary amino or quaternary ammonium groups in the bicarbonate salt form. The process is especially suitable for purification of crude glyoxal solutions such as are obtained by oxidation of acetaldehyde with aqueous nitric acid or by catalytic dehydrogenation of ethylene glycol. Comparative examples describe the purification of crude aqueous glyoxal solutions by the use of active carbon or by treatment with calcium carbonate.
